This invention relates to an improved attachment for gas engines.

An object ofthe invention is the provision of I a novel attachment for commingling a mixture of air and. fuel with: the

gases from the carbureter between the carbureter and the manifold to produce a more powerful mixture and improve running conditions of the engine.

Afurther object of the provide a device of this character which is composed of few and simple. parts, which maybe easily assembled and installed on an engine by an unskilled person and will not easily get out of order. v

' With these and other objects in view as will appear as the description-proceeds this invention consists of the. novel featuresof construction, combination of elements and arrangements of parts hereinafter to be fully described and claimed.

A full and complete understanding of the invention may be obtained from a consideration of the following detailed description,

taken in connection with the accom an in 2:

drawing'forming a part of this specification, it being understood that while the drawing shows a practical form of the invention, the latter is not to be confined to :50 strict conformity with the showing thereof,

but may be changed or modified, as long as such changes and modifications mark no material departure from the salient features of the invention as specifically pointed out and claimed.

In the drawing in which similar reference characters designate similar parts throughout the several views:

Figure 1 is a side elevation of the device of this invention in operative association ,Wlth the carbureter and inanlfold of. a gas engine,

Figure 2 is an enlarged longitudinal vertical sectional View of the device,

Figure 3 is a transverse vertical sectional view of the atomizer, and,

Figure t is an enlarged perspective of the perforated plug.

Referring to the specific embodiment of the invention illustrated in the'accompanying drawing the numeral 1 designates the atomizer plate which is formed to fit between the carbureter 2 and the manifold 3 of a gas engine and is held in position by The plate 1 is apertured as at '5 invention is to V bureter,

to aline with apertures (not shown) in the carburetor and manifold and is provided with a depending tube 6, the lower end'of which is threaded as at? for connection-t0 the elbow 8 of the pipe line 9 which enters the vaporizing-tank 10 adjacent the bottom thereof, I A

vA groove 1,1 v communicating with the passage through the tube-6 isprovided in the material of the plate 1 surrounding the lowerhalf ofaperture .5 and is bridged as In the vertically disposed nipple 13 is an .apertured partition 14, in which the tapered and .headed pin 15 normally rests. to close the passage through the line 9.

WVhen the 1 engine is running, the partial. vacuum created in the manifold permits the fluidin the line 9 to force the pin 15 up- ,wardly to a greater or less degree depending upon speed of the engine. c

The lower end of the pipe line 9 disposed within the tank 10 is closed and provided with an aperture 011 its under side. The partition16 divides the tank into two main v con'ipartments. Depending from the center envelope the gases from the car- Y which air is drawn into the tank. The valve 23 having an apertured operating lip 24 is screwed in the opposite end of the tube and may-be operated by a rod passing through the dash or may be operated with-the fingers. The end of the valve is connected by a pipe line .25 to a T connection 26, which is inserted in the main fuel supply line 27.

Great inconvenience has been experienced in starting engines by reason of the fact that the engine is cold and a richer mixture is needed to afford proper combustion. This device in addition to overcoming this difficulty by supplying additional air to the engine in combination with the original mixture, results in greater power with less fuel consuinption an annular groove partly encircling the Walls The peculiar arrangement of the tank forces. 1. the fuel and air to thoroughly IIIlX'lIl their passage down through the tube 17, through the] fuel which accumulates in the receptacle 18, out through the perforations '19 to the bottom of the tank, and throu h the pipe line 9 to the atomizer 1.- The additional fuel and'air furnishedto the motor in this manner insures ready starting and as soonas the motor is started and running evenly the valve 23 maybe closed and the entrance of air only through the atomizer into the mixture permits a greater amount-of power for any given opening of the main carbureter valve. i

1. A device of the character described comprising an atomizer plate havin a central aperture anda depending tubularportion, means for securing said platein opera tive position between the carbureter and manifold of a gas engine, said plate having of said aperture. and communicatin with the'inner end of the tubular portion, a ridge formed integrally with the plate traversing said groove, awvaporizer tank having a fuel feed line near the top thereof, an air in take in said feed line, means Within the tank for intimately mixing air' and fuel, and means connecting the tubular portion of the atomizer to the'lower portion of the tank.

2. A device of the class described comprisingan atomizer adapted to be operatlvely positioned between the carbureter and the manifold of a gas engine, a closed vaporize ing tank, independent fuellfeed linestothe carbureter and to the vaporizing tank, a valve and a T-joint having an apertured plug'associated therewith provided in: one

of said feed lines, and means connecting said atomizer to said tank and including a valve operable by the suction due to the vacuum in the engine. V 3. An attachment engines comprising a closed tank, a partition dividing said tank into an upper andlower compartment, an open ended tube depending from the center of said partition, a confor internal combustion tainer surrounding said tube and depending from the partition and having a series of spaced apertures near its top providing com munication between said lower compartment and the container, 'm-eansfor admitting fuel and air into the upper compartment, and

means permitting the passage thereof from the lower compartment to said engine.
